A kind-of-there idea I got by looking at a galaxy through my telescope and saying "Imagine if that was a big sapient entity flying around".

The foundation finds a big stellar construct made up of a huge number of stars, beamed together by pillars of solar energy that anomalously fly around the universe in weird directions. Everything is fine until they realise that the thingy came into view simply because it's after getting dangerously close to earth. The thingy slows down eventually. Meanwhile, an anomalous masked cult is appearing in wildernesses around Europe. They go around preaching about a "kinder god", a "great angel", a "beautiful father". The cult begins to die down as it is ignored, and the big star thingy disappears from view.

While the foundation is cleaning up any potential knowledge that there is a super mega ultra galactic magnetix set flying around calling itself "god", it appears again, this time even closer to our galaxy. The cult begins to preach in towns, outside Churches, on roads, etc… With the foundation detaining them and gunning them down in order to prevent information breaches.

The cult then begins to attack religious centres such as Churches, Mosques, and such. The foundation is killing them off rapidly, but this seems to be of little use, as they keep coming back out of nowhere. Until, there's a big flash of light and the thing is gone, and the cult has seemingly melted away.

The foundation later spot the stellar thingy far away getting its ass kicked by what seems to be an even bigger killgod entity. They see huge spears of energy being hurled into it, until eventually it dies out and is never seen again. This is essentially God killing some giant godlike creature because it thinks it's invincible, and the foundation was unable to do anything but watch.

Some other developments I've made are below:

The foundation puts the stellar thing in a double layered cover story. For the general public, it's a random undiscovered galaxy that moves fast and is very far away. For the unauthorised workers at the foundation, it's a strange potentially dangerous solar cloud that was believed to be God by some cult. For the authorised workers at the foundation (who can click the collapsible at the potential bottom of the potential article), it's what is described above.

Maybe the cult-people are made of stellar gases? As in, they are PART of the giant ego-pumped killgod?

Maybe the foundation picks up radio signals from it? Or from the super giant killgod that defeats it? Maybe it sounds a bit like an immature child that is very full of himself?

The foundation finds a big stellar construct made up of a huge number of "rogue" stars, beamed together by pillars of solar energy that anomalously fly around the universe in weird directions.

I uh… feel like you're going to need to do a fair bit of reading on astronomical phenomena and physics if you want to explain this in a way that people will believe is generated by a professional scientist.

Maybe the cult-people are made of stellar gases? As in, they are PART of the giant ego-pumped killgod?

Case in point, does this mean they're just… helium and hydrogen and stuff, then. (So they're basically party balloons?) Stars aren't made of anything that can't be found on earth in different forms.

Personally, I'm not too sure about this, mainly because I was getting a sense of "SCP-1548 (The Hateful Star), but with a cult slapped on", and kind of bad science.

Why does this thing exist anyway? Why does it have such a fixation on earth?

Your advice was really great and it really helps. I am gonna do research on astronomic phenomena. Yes, the cult are party balloons essentially. I couldn't have put it better myself. You're right in that the cult feels a bit tacked on, so I'm trying to improve on that. To be honest the cult is less of people (or balloons) who worship the giant constellation thing, and more so part of the giant constellation thing.

Why does this thing exist? Well, the original idea was that it was an angel, and the giant kill god that beats it up is Tetragrammaton or whatever. Not sure if that actually works, but hopefully I will be able to develop that one day with a bit of brainstorming power. Yes, my science is terrible (because I refer to the anomaly as x-thing most of the time), but that I will research and improve on when I work on tone if I make it to the writing stage. Why does it have such a fixation on earth? Who's to say it's JUST earth, and not just every life supporting planet in our stellar neighbourhood? >w>

Edit: I just brainstormed the angel thing, and with a bit of interest and a very VERY basic knowledge of physics, I got a bit of development. What if this thingy is an angel that fell millions of years ago, and because the light has only reached up now (and the beamed down cult), despite giant killgod being defeated agggeeesss ago? I'm thinking maybe Kokabiel from the Book of the Watchers? He is a fallen angel in a way, and is called the "star of God".
